First, stripe wirings A and B are set virtually intersect each other. A width of a strand of each of the stripe wirings A and B is set equal to/lower than a maximum line width decided by constraints imposed on a manufacturing process. Then, lengths of the strands in intersection portion of the stripe wirings A and B are compared with each other, and a longer strand is set as a strand to be changed for position. However, it is only a part of the strand in the intersection portion that is changed for position. Subsequently, an intersection point of center lines X and Y of the stripe wirings A and B is set as a reference position, and the strand to be changed for position is moved in a direction away from the reference position to a position where an occupancy rate of a wiring becomes equal to/smaller than a maximum occupancy rate of a wiring decided by constraints imposed on the manufacturing process.
